Can I wear my 6-month disposable contact lenses for a year? Which is better, non-ionic or silicone hydrogel?

There are many materials for cosmetic contact lenses, and many people don’t know how to choose. Can I wear six-month disposable contact lenses for a year? Which is better, non-ionic or silicone hydrogel contact lenses?

Can I wear my 6-month disposable contact lenses for a year?

Can't. Semi-annual disposable contact lenses need to be replaced every six months. Compared to annual disposable ones, semi-annual disposable ones have better oxygen permeability and are cheaper overall. The material is relatively superior, the contact lenses have good formability and are easy to wear, making them suitable for first-time wearers. However, cosmetic contact lenses have a high water content and will absorb more tears after being worn, which can easily cause your eyes to become dry.

Which is better for non-ionic and silicone hydrogel contact lenses?

1. Non-ionic material

This type of material has NVP ingredients added to it, which has a good moisturizing effect and can also balance the water content of contact lenses. It is light, soft and not prone to protein precipitation. It has very good adaptability and a long lens life, and is most popular among people with sensitive eyes.

2. Silicone hydrogel material

Silicon is added to this type of material to improve its water-locking ability. At the same time, the matrix contains many tiny "pipes" through which gas molecules and ions can pass freely through the lens. It is not restricted by the water content of the lens and can directly transmit oxygen in the air. Its oxygen permeability is 4-7 times that of ordinary materials. It is currently recognized as a material with high oxygen permeability. High oxygen permeability can relieve corneal hypoxia symptoms and reduce the incidence of keratitis.

I think you all understand that you can’t wear six-month disposable contact lenses for a whole year.
